[Interest] Row, Column, Repeater, and ListView spacer delegate?

[Jason H]

It would be really cool if Row, Column, Repeater, ListView supported a spacer delegate. So I could do:
A | B | C
And not just:
A  B  C

Is there a way I'm not thinking of? I don't want to include the bar in the delegate because then I always get an extra: either at the start or end of the list.
